What Is a Core Buildup? The Filling That Replaces Lost Tooth Structure Before a Crown

There is not enough tooth left to support a crown. Your dentist mentioned a core buildup — a material that replaces the missing tooth structure to give the crown something to grip. Here is what it involves.

Your dentist has told you that you need a core buildup. This sounds complicated, but it is actually a straightforward concept. A core buildup replaces missing tooth structure so that a crown can be placed.

Think of it as building a solid foundation for your crown. Without enough tooth to grip, the crown would not stay in place. The core gives the crown something to hold onto.


When Is a Core Buildup Needed?

A core buildup is used when a tooth has been badly damaged by decay or fracture. It is often done after root canal treatment. The tooth may be missing a large portion of its original structure.

If there is not enough tooth left above the gum line, a crown cannot be secured properly. The core fills in the gaps and rebuilds the shape of the tooth.


What Is the Core Buildup Made Of?

The material used is usually a composite resin or a glass ionomer cement. These materials bond to the remaining tooth structure. They are strong enough to support a crown.

Your dentist will remove any decayed or weak tooth material first. Then the core material is placed in layers and hardened with a special light. Once it sets, the tooth is shaped so that the crown will fit perfectly.


Is It Different from a Filling?

A regular filling repairs a small to moderate cavity. A core buildup is used when the damage is more extensive. The distinction is really about how much tooth structure is missing.

A core buildup provides the bulk and shape needed for a crown. A filling alone would not give the same result.


Does It Hurt?

Most of the time, a core buildup is done under local anaesthetic. You should not feel any pain during the procedure. After the anaesthetic wears off, your tooth might feel tender for a day or two. This is normal and should settle quickly.


How Long Does the Procedure Take?

A core buildup is usually completed in one dental appointment. It typically takes 30 to 60 minutes depending on the extent of the work needed.

If you are having a crown made, you will need a follow-up appointment. Your dentist will take an impression or digital scan of the prepared tooth.


Looking After Your Core Buildup

Once the crown is fitted, look after it as you would your natural teeth. Brush twice a day and floss around the crown daily. Attend regular check-ups so your dentist can monitor the restoration.

Do not hesitate to ask your dentist if you have any questions about the core buildup process.
